Description
Technical field
The utility model relates to a kind of constant low speed control system based on heavily joining AC drive diesel locomotive.
Background technology
At present, the permanent idling slow speed system of domestic AC drive locomotive adopts separately a control setup, and speed range is at 1 km/h～10km/h, error limit is larger, and can not be applicable to multi-locomotive, and actuation signal employing rigid line is given, has caused the waste of Internet resources.
The utility model content
The utility model has overcome shortcoming of the prior art, and a kind of constant low speed control system based on heavily joining AC drive diesel locomotive is provided.
The technical solution of the utility model is: a kind of constant low speed control system based on heavily joining AC drive diesel locomotive comprises the train locomotive microcomputer and is connected the read-out that is connected with the train locomotive microcomputer, permanent low speed setting potential device, train locomotive diesel speed control device, train locomotive main generator excitation controller; Described train locomotive microcomputer also carries out communication with the multi-locomotive microcomputer and is connected.
Compared with prior art, the utility model has the advantages that:
1) control integration of permanent low speed takes full advantage of the hardware resource of control system in locomotive level microprocessor control system, has reduced the Design and manufacture cost.
The control of permanent low speed when 2) having realized that three machines heavily join.
3) velocity control accuracy ± 0.1km/h, class of accuracy is high, has reached the leading level in the world.
4) Speed Setting is simple and convenient, can carry out reasonable distribution to multi-locomotive power according to actual condition.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is system architecture scheme drawing of the present utility model.
The specific embodiment
A kind of constant low speed control system based on heavily joining AC drive diesel locomotive, as shown in Figure 1, comprising: the train locomotive microcomputer be connected the read-out that is connected with the train locomotive microcomputer, permanent low speed and set potential device, train locomotive diesel speed control device, train locomotive main generator excitation controller; Described train locomotive microcomputer also carries out communication with the multi-locomotive microcomputer and is connected, and described multi-locomotive microcomputer is connected with multi-locomotive main generator excitation controller with multi-locomotive diesel speed control device respectively.
Described multi-locomotive microcomputer is at least two.
The permanent low speed setting value that permanent low speed setting potential device will be set in advance sends read-out to and shows, the train locomotive microcomputer is set according to the permanent low speed of read-out, enter the constant speed state of a control: the voltage signal that permanent low speed is set the potential device collection is converted to the constant speed speed in the 0.1-9.9km/h scope, and according to the power of train locomotive performance limit value, by the diesel engine speed of train locomotive diesel speed control device control train locomotive, by train locomotive main generator excitation controller control train locomotive main generator excitation; Simultaneously, connect by communication, the train locomotive microcomputer sends permanent low speed setting value to the multi-locomotive microcomputer, the multi-locomotive microcomputer is according to the power performance limit value of multi-locomotive, pass through respectively multi-locomotive diesel speed control device and multi-locomotive main generator excitation controller control diesel engine speed and main generator excitation separately, thereby realize the permanent low cruise of locomotive.
Principle of work of the present utility model is: the constant low speed control function is integrated in the locomotive level microprocessor control system, the power performance limit value of many locomotives that heavily join, the constant speed speed in the 0.1-9.9km/h scope, the startup of permanent low speed etc. are set at the computer display interface.Computer display and locomotive level microprocessor control system adopt the MVB network to carry out data exchange.Locomotive level microprocessor control system microcomputer is according to the situation of tractive load variation, ramp, bend, and the exciting current of auto-adjustment control diesel engine speed and main generator makes locomotive according to the constant operation of setting speed.
